Since the commercially available barrel pads are so long and bulky I decided to make a 20dB balanced L-pad (U-pad) out of a 2' XLR patch cable. The problem is it wont pass P48 or 12T power. It does work with dynamic mics, and attenuates as intended, but not with my condensers which of course is the reason I made it.
Not sure if i made it wrong or am missing something. Any suggestions?
I followed these instructions
